(This is an even much more detailed narration from Kairi, partly because she loves the gacha part... so, you could treat this as what she thinks she is in her own head.)

The departure of Valeria—or Agatha, as her true name resonated within the fundamental code of this world—was not a spectacle. There was no thunderous applause from the heavens, no weeping of the elements, and certainly no dramatic explosion of light to mark the exit of a creator.

Instead, space and time simply folded within the palm of her hand, a tidy collapse of reality that left the air tasting of static and old parchment. One moment, she stood there, a terrifying entity filling the Observatory with a pressure that threatened to turn my bones to powder; the next, she was gone.

The world felt suddenly, agonizingly empty.

But it wasn’t the emptiness of a vacuum; it was the clinical, sterilized silence of a stage after the actors had left and the stagehands had finished sweeping.

I stood frozen, my breath coming in slow, metronomic cycles.

My heart, which should have been hammering against my ribs in the wake of such a confrontation, beat with a disturbing, rhythmic precision. There was no lingering adrenaline, no phantom tremors of fear. It was as if my body had unilaterally decided to reset itself to its factory default settings. The fatigue that had weighed down my limbs moments ago had evaporated, scrubbed away by the "gift" she had left behind.

"No, there’s no need for that,"

she had whispered just before the end, waving away my attempt at a formal goodbye with the casual grace of a bored librarian.

"Just take this with you."

The particle of light she flicked into my chest hadn’t burned. It hadn’t felt like a blessing or a curse. It felt like data. It was a cold, efficient stream of information that integrated itself into my consciousness, a patch update being forced onto obsolete, glitchy software. As the sensation settled, her voice echoed one last time—not in my ears, but directly against the walls of my skull.

"Both you and Selene... turn out to be quite fascinating. She received something similar. You truly are anomalies, Kairi—uninvited guests to an event that was supposed to be so neatly organized."

Now, in the hollow silence of the Observatory, I felt the full weight of that anomaly status. The world felt honest for the first time. The background music of fate had been cut; the invisible safety net of the Author’s Intent had been retracted.

I was a character who had walked off the page and was now standing on the raw, unpainted floorboards of reality.

To distract myself from the existential vertigo, I closed my eyes and accessed the Library of Mind.

This mental space was my sanctuary, a sub-sector of my Visualization ability that I had cultivated back when I was still a student of the arcane—before my life became a series of life-or-death gambles. It usually appeared as a vast, dimly lit archive of floating scrolls and leather-bound tomes.

Today, however, something was different.

Resting atop a mahogany pedestal that shouldn’t have been there was a chest. It pulsed with a soft, predatory glow, radiating an aura that felt like luxury and danger intertwined.

The label hovering above it was unmistakable, written in shimmering neon-blue system text:

"Adultery Elixir of Life."

I blinked in my mind’s eye.

The name was typical Valeria—provocative, slightly mocking, and dripping with the aesthetic of a high-stakes adult gacha game. Beneath the title, a new notification flared:

[Spell Unlocked]

"A permanent unlock?"

I hummed to myself, my curiosity momentarily overriding the cold logic of my current situation.

"So it’s not just a one-time consumable. It’s a feature."

I reached out, and holographic symbols flooded my vision, displaying a detailed user manual written with Valeria’s characteristic perfectionism.

Effect: Allows the user to manipulate biological age and physical appearance at the cellular level. Infused with a high-potency vitality draught for instantaneous self-healing.

Duration: Infinite (dependent on the user’s available mana capacity).

Side Effects: Nausea, dizziness, vertigo, or severe anemia leading to potential syncope if usage exceeds the user’s mana reserves.

Additional Feature: Cancelable at any time.

At the very bottom, tucked away like a hidden Easter egg for the most dedicated players, was a tiny line of text:

[Bonus: Exclusive Outfit Skin Included – Auto Equip]

"A free skin?"

My gacha-addicted brain—usually buried under layers of cynicism—suddenly caught fire. In my old life, pulling a top-tier SSR unit was one thing, but getting the limited-edition Legendary-tier costume without spending a single cent was the ultimate high. Valeria knew exactly how to bribe me. She knew that beneath my cold exterior, I was still a girl who appreciated the aesthetic of appearances.

Ignoring Selene, who was still sprawled unconscious on the cold stone floor, I followed the mental prompts. My lips began to recite an incantation in an archaic Nordic tongue. The words felt heavy, like cold iron, yet they flowed from my mouth with terrifying naturalness.

"Eilífðar form, breyttu mér..."

The transformation didn’t manifest as a puff of smoke or a magical-girl sequence.

It was visceral.

No, it was biological.

I felt a radiance ignite within me—not a light for the eyes, but a glow at the cellular level. I could feel my DNA strands vibrating, as if invisible, dexterous fingers were clipping and splicing my genetic code, re-sequencing the algorithms of my very existence.

A configuration interface hovered in my sight:

[Kairi, please input age configuration by hours...]

I did the math in a heartbeat.

175,200.

Twenty years.

Slowly, surely, my bone structure shifted. I felt my height increase, my limbs lengthening, my muscles densifying and pulling taut. It was pure cellular regeneration accelerated ten-thousandfold. A strange, tickling sensation mixed with an ache so sharp it bordered on the erotic—the feeling of becoming something greater.

And then, the Skin manifested.

It wasn’t made of mere fabric. It was a high-level illusion weave, a manifestation of mana that felt as real as silk. I walked toward a large, silvered mirror in the corner of the observatory, my new, longer legs feeling strangely graceful. 𝙛𝒓𝓮𝒆𝔀𝒆𝙗𝓷𝒐𝙫𝒆𝙡.𝒄𝓸𝓶

I gasped.

The reflection was not Kairi—the thirteen-year-old girl with the weight of the world on her shoulders.

The woman in the glass was breathtaking.

She was elegant, mature, and radiated a terrifying nobility. Long, snow-white hair cascaded down her back like liquid silk, accented by golden floral ornaments and a pristine ribbon pinned to the left.

Her ears were slightly tapered—reminiscent of the elven queens of old—lending her a mystical, untouchable aura. Sharp sapphire-blue eyes stared back at me, framed by earrings of blue prism diamonds that caught the dim light.

The gown was a masterpiece of pure white, embroidered with gold thread so intricate it seemed to move. Her shoulders were exposed, skin flawless and pale, like marble untouched by dust or time.

"Incredible," I whispered, my new voice deeper, more resonant.

"This... this is Legendary tier."

For a fleeting moment, I was lost in the fantasy of my own power.

I wasn’t a pawn anymore.

I was the Queen.

But the euphoria was fragile.

From the hallway outside, the rhythmic, hurried thud of footsteps shattered my reverie...

"Crap," I hissed.

The Author might have left—but the rest of the cast was still very much here.

I moved instantly to cancel the spell, my heart hammering for the first time—not because of fate, but because of the simple, mortal fear of being caught.
